Note. Top panel, N = 938. In each cell, N = the number of children reporting engagement in the behavior; % refers to the percentage of the overall girls’ sample represented by the number. All behaviors are dichotomized yielding a range of 0–1.
Bottom panel, N = 968. In each cell, N = the number of children reporting engagement in the behavior; % refers to the percentage of the overall boys’ sample represented by the number. All behaviors are dichotomized yielding a range of 0–1.
Differences in frequency of binge eating and compensatory behaviors between genders were tested using chi-square analyses. None of the comparisons was significantly different at the p ≥ .001 level, indicating that the genders did not differ on the frequency of binge eating or compensatory behaviors.
